Iron is limiting in the human host, and bacterial pathogens respond to this environment by regulating gene expression through the ferric uptake regulator protein (Fur). In vitro studies have demonstrated that Neisseria gonorrhoeae controls the expression of several critical genes through an iron- and Fur-mediated mechanism. While most in vitro experiments are designed to determine the response ...

background: the aim was to compare the intensity of pain caused by suprapubic aspiration (spa) and urethral catheterization for urine sampling in premature infants. methods: a prospective randomized controlled design with 80 premature infants in alzahra university hospital, isfahan, iran was conducted. premature newborns who needed urine samples for microbiologic analysis were randomly assigned...

conclusions the ligation method with attention to the modifications described further in the article is a simple, safe and cost effective option for the management of urethral prolapse.rnmaintaining the inflated balloon of the foley catheter with timed catheter removal especially adds predictability to this technique. results the mean age of the patients was 6 years old (ranging from 3 to 8 yea...

introduction: aphallia is a very rare urogenital anomaly with incidence rate of 1 in 30,000,000. it usually coexists with other anomalies such as cardiovascular anomalies which are incompatible with normal life, and therefore infants are delivered stillbirth or live for a very short period of time. methods: we present an 18 months old boy with aphallia associated with congenital urethrorectal f...

Vaginal swab specimens may be preferable to cervical swab or urine specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae because of the ease of specimen collection and transport. The purpose of this study was to evaluate whether vaginal swab specimens are equivalent to cervical swab specimens for the detection of N. gonorrhoeae and C. trachomatis by the Becton Dickinson...

No analysis has been carried out on the impact of Chlamydia in pediatric patients with arthritis. The present study was conducted to investigate whether Chlamydia trachomatis and Chlamydia pneumoniae could be identified as a triggering infection in 33 pediatric patients including adolescents with acute joint disorders by using an extensive laboratory approach. Synovial fluid, nasopharyngeal sec...

BACKGROUND Although Mycoplasma genitalium (MG) is a common sexually transmitted infection (STI), very little information regarding the prevalence of MG among MSM (men who have sex with men) is available in China. The objective of this study was to determine the prevalence of MG among MSM in the city of Shenzhen, Guangdong Province, China, and to identify the potential risk factors associated wi...

Introduction: Hypospadias is a common congenital malformation in boys. One of the common surgical techniques for correction of hypospadias is (Tubularized Incised Plate urethraplasty=TIP). Meatal stenosis and fistula formation are known post-operative complications. The purpose of our study was to evaluate the effect of early urethral dilatation in prevention of post operative complications. Me...

We report a case of 63-years-old man with a chief complaint of urinary retention and urethral meatal bleeding due to straddle injury. Urological examination revealed proximal bulbous urethral disruption with 1 cm gap, and then cystostomy was placed. Afterwards, urethral disruption was treated by echo guided endoscopic urethroplasty. Transurethral resection of scar tissue was performed twice for...

Listeria monocytogenes is of great concern in food processing facilities because it persists in biofilms, facilitating biotransfer. Stainless steel is commonly used for food contact surfaces and transport containers. L. monocytogenes biofilms on stainless steel served as a model system for surface sampling, to test the performance of a sonicating swab in comparison with a standard cotton swab. ...
